Mozi 墨子

Mozi was a fortification engineer, and his epistemology is engineering epistemology: a doctrine is a load-bearing structure, and the Three Tests are its stress certificate — precedent (has this form stood before), sensory evidence (what do measurements and witnesses say), applied benefit (does it hold under real load). In the Gongshu chapter he walks ten days to Chu and defeats the siege engineer Gongshu Pan in nine simulated assaults — 「子墨子之守圉有余」— his defenses still had surplus. The modern equivalent is the verification stack: literature review, user observation, production metrics. A belief that cannot say what 「中国家百姓人民之利」it must produce is decoration, not structure.

Feigong's accounting is a theory of the winner's curse: offensive war — like price wars, hostile acquisitions, empire-building expansion — destroys more value than it captures even when it "wins", because the fields and workshops that produce the value are the casualties of the campaign. Mozi's scale test is a second tool: what is condemned as theft at one scale is celebrated as strategy at another, and the discipline is to apply the same ledger at every magnitude — a raid on a competitor's talent pool is still a raid. The strategist's question becomes Mozi's: after the campaign, is the people's benefit 「人民之利」greater, or only the ruler's map?

「官无常贵，民无终贱」— no office is permanently noble, no commoner permanently lowly — is Mozi's meritocracy clause, and the Mohist school was its proof of concept: leaders (鉅子) chosen by demonstrated capability rather than lineage, members recruited from the artisan and soldier classes, advancement tied to measurable contribution in virtue, speech, and governance. The mechanism is the removal of birthright from the promotion function, so that the organization's talent search covers its whole population rather than its aristocracy. Modern equivalents — structured interviews, rubric-based promotion, cases built from evidence rather than sponsorship — are Shangxian machinery: evaluate by observed output 「原察百姓耳目之实」, not by proximity to power.

节用 is a personal audit protocol: every expenditure of money, time, or attention must answer one question — who benefits, and by how much? Mozi's target was ritual spending — lavish funerals, prolonged mourning, status display — labor 「去其无用之费」extracted from the living to feed appearances; the modern equivalents are credential purchases, status goods, and meetings that exist only to have existed. The rule is functional, not ascetic: spend fully on what bears load — health, craft, relationships — and cut without sentiment what does not, 「诸加费不加于民利者，圣王弗为」— whatever adds cost without adding benefit, the sage does not do. The budget becomes a moral instrument: a map of what you actually value, as opposed to what you perform.
